DEVICE FOR SPINNING AND TWISTING TEXTILE FIBERS.

Application filed April 7, 1911, Serial No. 619,476.

T 0 all whom it may concern:

Be it known that I, VIo'roR BnLANenR, citizen of the United States, and resident of Marshfield, Massachusetts, county of Plymouth, have invented certain new and useful Improvements in Devices for Spinning and Twisting Textile Fibers, of which the following is a specification.

This invention relates to the art of spinning and is an improvement upon the type of spinning machine shown and described in my earlier co-pending application Serial Number 595,187. The present improvement is intended to render more easy and certain the action of the rotary yarn-engaging device which cooperates with the spindle member by providing a novel form of connection between these two members and further by providing an improved form of cap-supporting or lifting device in order to more effectively control the action of said cap or yarn engaging member.

Another improvement set forth herein has relation to the adjustment by which the relations of the controller and the rotary cap are adjusted in order to regulate the tension. Another feature of the present invention consists in providing'an extensible portion for the spindle member adapted to permit the cap to be raised so as to build the cop the full length of the spindle member or bobbin.

These and other features of the invention will be more particularly explained in detail with the aid of the accompanying drawings of which- Figure 1 is a side elevation partly in central section showing the relations of principal parts.

Fig. 8 is an elevation partly in central sec- 7 tion showing the relation of the parts and of the controller adjusting means. 7

sion member to the bobbin proper and to the cap.

Figs. 13, 14 and 15 are views in detail of modified forms of construction by which the extension member is connected with the cap.

As in my former specification I will use the term spindle member as applicable either to the cop tube or bobbin when the yarn is wound upon a detachable bobbin or to the spindle itself when the yarn is wound on the bare spindle without the intervention of a cop tube, although in general practice the former is far more usual.

In the practice of my invention according to the form illustrated in the drawings, I employ the rotary spindle member a and a cap 7) which may be of any suitable shape adapting it to be connected to the spindle member at one end by means of a sliding engagement or connection, its other end being formed with a smooth yarn engaging edge which serves by its engagement with the yarn to assist the revolution of the yarn about the axis of rotation while allowing the yarn to lag or slip, in order to cause it to wind upon the spindle-member.

To secure the proper engagement between the spindle-member and the yarn engaging member or cap, I employ an intermediate coupling member or clutch member I), which is so to speak, insulated for the most part from the adjacent portion of the cap by means of any suitable shock or vibration absorbing device. This shock absorbing device is intended to prevent the transmission of vibration between the spindle and the cap, and it may consist simply of an annular band or tubular piece 6 ofyielding mate rial such as textile or other fibrous material, rubber or the like, or a piece of spring metal. The clutch 7) is centrally bored to fit around thespindle with a slight degree'of play or looseness and should have such locking engagement with the spindle member as will cause it to rotate in unison with the spindle, this being effected in this instance by means of a key 5 fitting into one or more keyways or grooves 61 extending lengthwise of the spindle member. The clutch is prevented from turning in relation to the cap by means of the stud or screw 5 which projects from the outside of the clutch through a corresponding hole or opening in the cap,

' ferential adjustment of the bolster.

The lifting or cap supporting member in this case is shown as a wheel a mounted in an anti-friction bearing and having one annular supporting face 0 adapted to proj ect beneath the overhanging edge of the cap 6 to give vertical or axial support to the ca and having another bearing surface 0 whic affords lateral support or engagement with the said cap in order to steady it against lateral vibration. It is the function of this pivot wheel both to sustain the cap. vertically and to keep the cap disengaged from centrifugally clutching the spindle, so as to permit a free axial movement without binding between the cap and the spindle member. I prefer to overhang slightly the lateral face 0 of the pivot wheel and also to give the bearing face 0 of the wheel a slight bevel or inclination.

I also prefer to mount the pivot wheel so as to give it a slight yielding pressure laterally against the cap, and the construction by which this is accomplished according to the form illustrated in the drawings is as follows:

The wheel 0 is carried by a shaft 0 with a conical foot which is supported in a bushing 0' in which are perforations near the top and the bottom and whose periphery is fluted to form vertical channels for the flow of oil. The bushing c is supported in an oiltube c in the bottom of which is an elastic cushion 0 The oil tube 0 is carried in an eccentrically bored holder 0 a sleeve 0 of fabric being interposed to form an annular cushion around the oil tube. The holder 0 is carried by a bolster 0 clamped into the copping rail cl by a nut 0 to permit circum- The holder 0 is given a'slight torsional pressure by means of a spiral spring 0 anchored to a fixed block 0 and having its upper end secured to the holder so that the shaft hearing and the wheel itself are pressed with 'a light yielding pressure toward the cap 6. The bearing portions 0, 0 of the wheel may be made ofany suitable material, but I prefer a relativelysoft substance like felt or leather, which maybe clamped in place between rigid members or washers. I prefer to construct the wheel so that the upper lateral. bearing 0 will engage the shaft above the bearing face 0 for better support. A controller plate 6 is mounted on the rail din position to engage and retard the revolving yarn acent to the edge of the cap. The extent of retardation and hence the tension ofthe yarn will depend upon how far the upper indented edge e of the controller 6 projects above the lower edge of the cap. As the vertical position of the cap is determined by the pivot wheel 0 said adjustment may be effectedby adjusting the pivot wheel vertically or by adjusting the controller verti cally. In Fig. 1, I have shown the pivot wheel provided with a vertical adjustment, while in Fig. 8, I have shown the controller provided with the vertical adjustment. In Fig. l, the controller plate is shown mounted upon a shock absorbing cushion or washer 0 Any suitable form of adjusting device may be employed in the form illustrated in Fig. 1. The oil containing tube 0 forming part of the bearing support for the pivot wheel is provided at its upperedge with a radial flange 0 which is engaged by the inclined raised portion f of an adjustable strip 7 which extends the whole length of the rail, the raised portions being struck up from the sheet'metal as shown in Figs. 6 and 7 in a proper position to pass beneath and engage the flange 0 on opposite sides. The metal portion of the strip 7 is cut away to form an aperture to receive the body of the tube 0. Obviously a longitudinal movement of the adjusting bar or strip 7 will act by reason of the inclined surfaces 7 to raise the tube 0 or to allow it to drop according to the direction of its movement. The bar is locked in its position of adjustment by means of a suitable device, such as set screws 7.

In Fig. 8, I have shown the same form of adjusting strip applied to the controller instead of to the pivot wheel. In this case the controller 6 is provided with an annular flange e and is made long enough to ex tend through the spindle orifice in the rail cl, so as to be guided thereby. I also use a spiral compression spring 6 which serves normally to depress or turn down the con troller plate, while allowing it to rise under the action of the adjusting bar or rail 7.

Since the yarn can be delivered to the spindle member only from the bottom of the cap, and since the top of the cap must al ways engage the spindle member, it is obvious that when using an ordinary cop tube on a spindle, the cop tube cannot befilled clear to the top. To obviate this objection I have provided a removable extension mem ber g, which corresponds in cross section to the cop tube or bobbin which it registers with when in position. This extension member g is provided with a downward extension 9 of smaller diameter tlianthe cap engaging portion, this smaller part being provided with longitudinal slots which divide it as shown in Figs. 9 and 10 into three spring members or fingers g capable of being compressed toward each other to pass inside the upper end of the cop tube proper,

members from falling apart when removed from the spindle for doffing, I have provided means which serve to interlock these two members together when the cap is raised to the top of the extension member. This retaining means may be of any suitable form, and in Fig. 9 is shown to consist of a tubular cap [L of spring metal secured to the top of the extension piece and slotted axially and radially, as shown in Figs. 9 and 12, to make the lower edge of the tube compressible and extensible. Under this lower edge the tube is formed with an annular projecting lip 71/ adapted to pass inside of and engage the inwardly projecting annular lip Z) formed in the clutch member 5 By this means the cap when pushed toward the upper end of the extension member 9 is automatically but detachably interlocked with the extension piece.

Various other means may be used for effecting this interlocking engagement, such for example, as that shown in Figs. 13 and M, in which the portion of the extensible member forming the bottom of the groove engaged by the key of the cap is severed from the rest of the extension piece .9, so as to form a yielding notched spring lip 9 adapted to engage and interlock with the key 6 of the clutch member.

In Figs. 14 and 15, I have shown a split ring 2' one end of which is turned in to form a projection i to pass through the upper end of the cap and engage a hole bored in the clutch member 5. This spring is preferably seated in an annular groove formed on the exterior face of the cap, as shown in Figs. 8 and 14.

It will be understood that when the controller or tension device is not in operative position to perform its function of retarding the yarn that the retardation .of the yarn will be caused by the ballooning of the yarn due to centrifugal action and the resistance of the air. Obviously the ballooning and the resistance will be greatest, other things being equal, when the length of the ballooning yarn is greatest, and will be diminished as the cap approaches the top of the spindle. To equalize the tension on the yarn between the thread-eye and the cap, I employ means for lifting the thread-eye as the cap approaches the top of the spindle. This may be accomplished in a variety of ways but for the purpose of illustrating the principle, I have shown in Fig. 8 the threadeye m mounted on the vertical shank m secured to the lifting rail cl by means of an adjusting set screw. With the arrangement just described the thread-eye will always be a uniform distance above the bottom of the cap and consequently the length of the ballooning yarn will be the same whether the lifting rail be near the bottom of the cop or the highest point of its traverse.

WVhile this invention has been shown and described as applied to the art of spinning, it will nevertheless be understood that it is based upon the discovery of the mechanical principle that two concentric bodies rotating at high speed may be prevented from being clutched together by centrifugal action by arranging an independent member so as to engage one of the rotating bodies at a point outside of the axis of rotation, but so as to allow the rotation, and upon the further principle that the interposition of a shockabsorbing device or medium between the two bodies still further facilitates the neutralization of such centrifugal clutching action. The neutralization of this centrifugal engagement is important because it allows one member to move freely axially of the other member, and as this movement is desirable in many mechanical devices besides spinning machines, I do not confine the use of the new combinations herein set forth and claimed to such machines.-
